The invention discloses a series brake parachute system which comprises a main parachute, a brake parachute and at least two connecting ropes, and a parachute top hole is formed in the parachute top of the main parachute; the area of the brake parachute after being inflated is smaller than the area of the parachute top hole after the main parachute is inflated; and one end of each connecting rope is connected with the parachute top of the main parachute. The main parachute has the advantages that part of airflow entering the main parachute flows to the rear of the center of the main parachute through the parachute top hole, it is guaranteed that the airflow field behind the center of the main parachute is good, and conditions are provided for normal inflation and stability of the brake parachute; the length of each connecting rope can be greatly reduced, fluctuation similar to ship movement caused by the fact that the connecting ropes are too long is avoided, inflation stability of the series parachute system is guaranteed, the overall length of the series parachute system is greatly reduced, and the weight of the series parachute system is reduced.
本发明公开了一种串联减速伞系统,其包括主降落伞、减速伞及至少两个连接绳,所述主降落伞的伞顶开设有伞顶孔;所述减速伞充气后的面积小于所述主降落伞充气后所述伞顶孔的面积;各个所述连接绳的一端均与所述主降落伞的伞顶连接。本发明的有益效果是:进入主降落伞的部分气流通过伞顶孔流向主降落伞中心后方,保证了主降落伞中心后方的气流流场良好,为减速伞的正常充气和稳定提供了条件,同时,因为主降落伞中心后方的气流流场良好,可以大大的降低各个连接绳的长度,避免连接绳过长,产生类似船舶运动的波动,保证了串联伞系统充气的稳定,还极大地减小了串联伞系统的整体长度,并降低了串联伞系统的重量。
